Web20 mei 2024 · Mine recovery and dilution are used in mine planning and reconciliation process and are centred around ore tonnages while mill recovery is used in metallurgical process and cut-off grade calculation and is centred around metal quantity. The document aims to briefly explain the terminologies and their applications. Webmeasure the dilution ranges in each region. The methodology considers the uncertainty associated with the ore grades to verify the probability of occurrence of dilution in the short-term mine plan. The results demonstrated that the use of uncertainties enabled identification of the areas with a higher potential of incurring operational dilution.
